Last little bit of LR3

As we all know IGF-1LR3 is a bit exspensive ,I´ve tried to
dilute the last little bit in the vial of MR´s Lr3 IGF-1 with a
couple of cc hgh in water.

I´ve seen the Ba floating around in bubbles and wanted to make 2-3
shots out of it,but a day after dilution,a whitish stain formed on the
vial bottom and wall,nearly no more BA-bubbles.

I expect this to be the IGF which has fallen out the solution.
Is there a way to get it into solution again,or is it lost,degraded,or
anything like that?
How about a mild acid about .10%hcl or stronger something like that,might that help?

That's odd. That's how I get the last bit out too....I've used water or BA, but I've never seen it precipitate. How much did you have left when you added the water? What total volume is in there now? The BA will work as a slight buffer, but if you know the total volume and have access to HCl and a filter, then you can just add enough HCl to get the final solution to roughly 10mM HCl.
